Whats your battery life?

Im beginning to think there is something wrong with my phone. As you can see from the screenshots ive only used the phond for 3 hours and 41 minutes on low screen level and im at 20% ...the battery monitor history screenshot shows my miliamp usage to be between 300ma - 1000ma...considering the phone only has a 2100mah battery that means at an avg use of 500ma I can only get 4 hours of use. Is that what everyone else is experiencing?

On a normal use day I get about 16-17 hours. On a heavy use day maybe 13-14. I was also having battery issues, and with that same "normal" use I'd get about 8 hours. So if you get anything less than my original times, something is wrong. I suggest using GSAM instead of the stock battery monitor. It'll give you a more specific idea of what's happening. You can also try WatchDog, which monitors CPU use, but it never really helped me so...

Also I know that if a browser is left open in the background it can cause massive battery drain. So it looks like Firefox was a top user, so maybe for whatever reason it's not closing. Are you in an area with weak service?
